- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Add an elf note on ARM to store the MACHINE_ARCH an executable was built
for. This is useful for software needing to know which architecture a
binary is built for as arm and armv6 have slight differences meaning only
some binaries build for one will work as expected on the other. It is
expected pkgng will be able to make use of this to simplify the logic to
determine which package ABI to use.

Improve readelf notes output for Linux ELF files

Add four ELF note constants:
- NT_FILE and NT_SIGINFO (core file notes output by recent Linux kernels)
- NT_GNU_ABI_TAG (was incorrectly reported as NT_VERSION)
- NT_GNU_BUILD_ID (used for locating standalone debug files)

Handle FreeBSD-specific ELF notes

Add a function to return the specific type, when the note's Name field is
'FreeBSD'.

r249558 added FreeBSD-specific ELF note types that reuse type numbers of
existing generic / Linux types. This caused 'readelf -n' to produce
incorrect output on FreeBSD core files.

Handle DW_TAG_rvalue_reference_type

2012-05-21 Jim Ingham <jingham@apple.com>

* dwarf2read.c (process_die): Handle DW_TAG_rvalue_reference_type.
(read_type_die): Ditto.
(dwarf_tag_name): Ditto.

* elf/dwarf2.h: Add DW_TAG_rvalue_reference_type.

Fix the value of NT_FREEBSD_TAG to be the same as ABI_NOTRTYPE in lib/csu.
Add NT_FREEBSD_NOINIT_TAG for the value of CRT_NOINIT_NOTETYPE.
Check for both of these when detecting a FreeBSD binary in gdb.

Extend GDB to check the value in the .note.tag section along with the
.note.ABI-tag section.

This helps on ARM EABI where the OS/ABI field is zero. It would be better
to use the NOTES program header however this would require a more invasive
change.

Teach gdb about the DW_FORM_flag_present dwarf attribute, so it doesn't
error out on files that contain it. (This attribute can be emitted by
newer versions of clang.)

Merge binutils 2.17.50 to head. This brings a number of improvements to
x86 CPU support, better support for powerpc64, some new directives, and
many other things. Bump __FreeBSD_version, and add a note to UPDATING.

Thanks to the many people that have helped to test this.

Add the ability for GDB to printout the thread name along with other
thread specific informations.

In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
- For cores, a new ELF note is added (NT_THRMISC) that can be used for
storing thread specific, miscellaneous, informations. Right now it is
just popluated with a thread name.

GDB, then, retrieves the correct informations from the corefile via the
BFD interface, as it groks the ELF notes and create appropriate
pseudo-sections.

Add support for the BFD target efi-app-x86_64.

This uses only GPL2 source code and is a requirement for a 64 bit EFI
boot loader.

Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.

o) Add TARGET_ABI to the MIPS toolchain build process. This sets the default
ABI to one of o32, n32 or n64. If it is not set, o32 is assumed as that is
the current default.
o) Set the default GCC cpu type to any specified TARGET_CPUTYPE. This is
necessary to have a working "cc" if e.g. mips64 is specified, as binutils
will refuse to link objects using different ISAs in some cases.
o) Add support for n32 and n64 ABIs to binutils and GCC.
o) Add additional required libgcc2 stubs for n32 and n64.
o) Add support for the "mips64r2" architecture to GCC. Add the "octeon"
o) When static linking, wrap default libraries in --start-group and
--end-group. This is required for static linking to work on n64 with the
interdependencies between libraries there. This is what other OSes that
support n64 seem to do, as well.
o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the
former being what libgcc, etc., check and the latter seemingly being a
misspelling of a hand merge from a Linux spec.
o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default
ISA from the ABI. Our old defaults were too liberal and assumed that 64-bit
ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to
the MIPS32 ISA, when we are supporting or will support some systems based on
earlier 32-bit and 64-bit ISAs, most notably MIPS-III.
o) Merge a new opcode file (and support code) from a later version of binutils
and add flags and code necessary to support Octeon-specific instructions.
This should also make merging opcodes for other modern architectures easier.
